Perhaps along with the fact that they don't allow for thousands of miles of travel on a single charge, electric vehicle batteries do have a shortcoming – they're only as good as their weakest cell. That's because all their 100-plus cells are connected in series, meaning that if one of them dies, then the whole battery pack stops working. That could be about to change, however, thanks to research being carried out at Germany's Fraunhofer Institute for Manufacturing Engineering and Automation.Read More
Using millions of tiny fibers of nanocellulose sheathed with a conductive polymer coating, scientists have created sheets of paper that can store significant amounts of electric charge. Dubbed "power paper," the material is able to be recharged many hundreds of time, and in mere seconds. It is also lightweight, requires no toxic chemicals or heavy metals to create, and may offer a renewable and prolific way to provide energy to all manner of devices.Read More
Scientists at the University of Maryland and the US Army Research Laboratory have used high concentrations of salt in water to create safe, green batteries that could find use in anything from large-scale grid storage to spaceships and pacemakers.Read More
At the COP21 climate change summit currently taking place in Paris, a one-of-a-kind prototype Renault delivery van powered by second-life batteries taken from decommissioned electric cars is being showcased. The project is part of an initiative to show how used electric vehicle (EV) batteries can be repurposed before full recycling.Read More
A team of researchers in France has taken a major step towards powering our devices with rechargeable batteries based on an element that is far more abundant and cheaper than lithium. For the first time ever, a battery has been developed using sodium ions in the industry standard "18650" format used in laptop batteries, LED flashlights and the Tesla Model S, among other products.Read More
With theoretical energy densities as much as 10 times that of current lithium-ion batteries, lithium-air (or lithium-oxygen) batteries hold tremendous potential for storage of renewable energy and use in mobile devices and electric cars. Although a practical lithium-air battery is still some years from becoming a commercial reality, researchers at the University of Cambridge have developed a working laboratory demonstrator that shows how many of the problems holding back the development of lithium-air batteries could be overcome.
As energy production moves towards solar and wind-powered alternatives, battery systems to store intermittently-produced electricity have never been more important. Unfortunately, many of the materials needed to make high-performance batteries for this purpose are rapidly diminishing and becoming increasingly expensive as a result. Now researchers have created a new type of storage battery that is made from a range of cheap and abundant materials and shows promise for high-efficiency performance.Read More
As electric cars come towards the end of their life, they create a set of problems that you simply don't get with petrol cars - namely, getting rid of the batteries. Automotive giant Daimler is doing its bit to tackle the problem by partnering with The Mobility House, GETEC and Remondis to create a 13-MWh battery storage unit out of second-life battery systems from electric and plug-in hybrid cars.Read More
The number of electric vehicles and mobile devices is expected to surge over the coming decade, which would place considerable strain on our environment and resources as far as battery technology currently stands. In an effort to find more sustainable alternatives for battery materials, researchers from the University of California, Riverside have created a battery incorporating the skins of portabella mushrooms. The move not only has the potential to reduce the economic and environmental cost of battery production, but may also result in batteries whose capacity increases over time.
While we've previously seen a number of GoPro accessories which can keep you shooting when the battery runs out, the PolarPro PowerGrip H2O is the first we've come across capable of live-charging the action camera while underwater. Currently looking for funding on Kickstarter, the PowerGrip H2O is a waterproof selfie stick with an integrated battery, which can charge a camera at depths of up to 30 m (99 ft).Read More
